Rotary actuator outputs

The actuator outputs are used when a 4-wired rotary actuator is installed in your application. The integrated electronic

governor in the SGC controller is used together with the actuator to create an electronic governing application for

mechanical fuel engines. In diesel engines, the shaft output in the actuator is mechanically connected to a stop lever or the

throttle level in a fuel injection pump, for example. For petrol and natural gas engines, the shaft output is connected the

throttle or charge control valve.

Use one of these methods for the CT ground (S2) connections:

1. The S2 terminals are not grounded. The controller detects the current accurately.

2. The S2 terminals are grounded at the GND terminal (terminal 1).
